A lower guide portion 14 is formed in the lower protruding portion 12. A main inflow hole 13 through which fluid flows is formed at the lower end of the lower guide portion 14. Preferably, the main inflow hole 13 is formed to be tapered downward as shown in the drawings. A stepped portion 15 having a diameter greater than that of the lower guide portion 14 is formed in the lower protruding portion 12. The stepped portion 15 is preferably inclined as shown in the drawings. Here, a plurality of sub-inflow holes 13a through which fluid flows may be formed in the stepped portion 15. The outer coupling cover 20 is coupled to the protruding portion 1 a of the bottle 1 while accommodating the inner cover 10 by being pressed by a well-known press (not shown) forming a seal. An upper guide portion 24 corresponding to the lower guide portion 14 and at least one flow hole 23 having a diameter less than that of the upper guide portion 24 are formed at the outer coupling cover 20. Also, a threaded portion 21 is formed at the outer circumferential surface of the outer coupling cover 20.
A rim 22 for preventing liquid from flowing along the outer circumferential surface of the outer coupling cover 20 due to surface tension, is formed at the upper end of the outer coupling cover 20. The rim 22 is naturally formed by forming a recess 22a along the outer circumference of the upper end of the outer coupling cover 20.
The valve member 30 is installed between the lower guide portion 14 and the upper guide portion 24 to be capable of moving. A first blocking protrusion 33 for blocking the main inflow hole 13 and a second blocking protrusion 35 having a diameter greater than that of the first blocking protrusion 33 are formed at the valve member 30. An inclined surface corresponding to the main inflow hole 13 which is tapered is formed at the end portion of the first blocking protrusion 33 while an inclined surface corresponding to the stepped portion 15 is formed at the second blocking protrusion 35. Also, flow grooves 37 along which liquid can flow are formed in the upper portion of the second blocking protrusion 35 of the valve member 30 in a lengthwise direction. The first blocking protrusion 33 of the valve member 30 blocks the main inflow hole 13, and simultaneously, the second blocking protrusion 35 blocks the sub inflow holes 13a and the lower guide portion 14. The screw-off cover 40 is screw-coupled to the threaded portion 21 of the outer coupling cover 20 so that the rim 22 and the flow hole 23 are completely enclosed.
The operation of the bottle cap for preventing the intrusion of foreign materials having the above structure according to the first preferred embodiment of the present invention, will now be described with reference to FIGS. 4 and 5.
Referring to the drawings, when the bottle 1 stands upright, as the valve member 30 moves downward due to the weight thereof, the first blocking protrusion 33 blocks the main inflow hole 13 and the second blocking protrusion 35 coupled to the stepped portion 15 blocks the lower guide portion 14 and the sub-inflow holes 13a. In this case, if one intends to insert foreign materials through the flow hole 23 form the outside, since the first and second blocking protrusions 33 and 35 block the main and sub- inflow holes 13 and 13a and the lower guide portion 14, the intrusion of the foreign materials into the bottle 1 is prevented. Furthermore, since the diameter of the second blocking protrusion 35 is greater than that of the flow hole 23, if one tries to insert foreign materials into the bottle 1 by using a syringe, a needle of the syringe is blocked by the second blocking protrusion 35 so that the intrusion of the foreign materials is prevented. When the bottle 1 is held upside down to pour out its contents, as the valve member 30 moves due to its weight, the first blocking protrusion 33 opens the main inflow hole 13. As the second blocking protrusion 35 is separated from the stepped portion 15, the sub-inflow holes 13a and the lower guide portion14 are opened. Then, the contents of the bottle 1 flow out through the main and sub-inflow holes 13 and 13a, the lower guide portion 14, the flow grooves 37 and the flow hole 23.
FIG. 6 is a sectional view of the bottle cap of FIG.1 according to a second preferred embodiment of the present invention, and FIG. 7 is a sectional view of the bottle cap of FIG. 6, in which the intrusion of foreign materials is prevented by the valve member.
